Which expression is equivalent to 3^6 * 3^8? Choices: (A)3^48 (B)1/3^48 (C)3^14 (D)1/3^14

Identify Base and Exponents: Identify the base and the exponents. In the expression 3^6 * 3^8, the base is 3, and it is raised to the exponents 6 and 8, respectively. Base: 3 Exponents: 6, 8Apply Multiplication Rule: Apply the rule for multiplying powers with the same base. When we multiply powers with the same base, we add the exponents. 3^6 * 3^8 = 3^(6+8)Perform Exponents Addition: Perform the addition of the exponents. Calculate the sum of the exponents 6 and 8. 6 + 8 = 14Rewrite Expression with Combined Exponent: Rewrite the expression with the combined exponent. Replace the sum of the exponents in the expression. 3^6 * 3^8 = 3^14Choose Equivalent Expression: Choose the equivalent expression for 3^6 * 3^8. From the given choices, 3^14 is the correct equivalent expression. So, the final answer is (C)3^14.
